I have a situation and I am not sure how it should have been billed. Patient came in for her colon and the dr discontinued because of poor prep. Patient then came back in the afternoon and the dr did complete the colonoscopy. We billed 45378-53 and 45385-76. Of course bluecross denied the 45378-53. Is this the proper way to code this? I have never billed for the procedure being repeated on the same day.
